Damn, beat me to it Lyle.
I think that either B and C or C and D are used in the beginning of Stinkfist (the high pitched part before the feedback comes in). He didn't use them much on Aenema but there all over the place on Lateralus. I think he's been using the same Sonor set since the Opiate days.
Yea, Danny's set owns

, f**king kickass drummer, just as good in VOLTO! too, his other band.
